Abstract: Records of the Student Mobilization Committee to End the War in Vietnam (SMC), a national coalition (1966-1973) formed to coordinate opposition to U.S. involvement in the war in Vietnam among college and high school students. Best represented is the early period (1966-1968) when the national office was headquartered in New York City. Most complete are the files on anti-war groups in California (some correspondence from Bettina Aptheker is included here), Illinois, Massachusetts, Michigan, and New York. Most extensive international contacts involved Australia, Canada, France, and Vietnam. Other files concern the G.I. Press Service, an arm of SMC which organized anti-war sentiment in the military.
